System commands control system functions that are not directly related to output control, measurement, or status functions. Common commands are also used to control system functions.
SYSTem:COMMunicate:RLSTate LOCalREMoteRWLock
SYSTem:COMMunicate:RLSTate?
This command configures the remote/local state of the instrument according to the following settings.
LOCal The instrument is set to front panel control (front panel keys are active). REMote The instrument is set to remote interface control (front panel keys are active).
RWLock The front panel keys are disabled (the instrument can only be controlled via the remote interface).
The remote/local state can also be set by interface commands over the GPIB and some other I/O interfaces. When multiple remote programming interfaces are active, the interface with the most recently changed remote/local state determines the instrument’s remote/local state.
The remote/local state is unaffected by *RST or any SCPI commands other than SYSTem:COMMunicate:RLState. At
